KDiskMark as a Linux alternative to CrystalDiskInfo

Updated

Our verdict

KDiskMark is not a replacement for CrystalDiskInfo. It benchmarks read/write speeds but does not read SMART data, show health status, temperature, or power‑on hours. Users who only need performance testing can use it, but those monitoring drive health should stick with CrystalDiskInfo or a Linux tool that reads SMART, like smartctl or gnome‑disk‑utility.

What works the same

  • Both run on Linux
  • Both are free and open‑source
  • Both can be used from the command line
  • Both provide some form of report output

What is different

  • KDiskMark measures performance, not SMART attributes
  • CrystalDiskInfo shows health status (Good/Caution/Bad)
  • CrystalDiskInfo reports temperature and power‑on hours
  • CrystalDiskInfo supports NVMe monitoring
  • KDiskMark has no GUI and no notifications for critical issues

Opening your CrystalDiskInfo files

CrystalDiskInfo stores data in its own proprietary format; KDiskMark cannot open or export those files. If you need to migrate data, you would need to export SMART data from CrystalDiskInfo as a CSV or text file and then import that into a Linux SMART viewer.

Switching from CrystalDiskInfo to KDiskMark, step by step

  1. 1. Export SMART data from CrystalDiskInfo to a CSV or text file.
  2. 2. Install a Linux SMART viewer such as smartctl or gnome‑disk‑utility.
  3. 3. Import the exported data into the Linux tool if it supports CSV import, or manually note the values.
  4. 4. Use the Linux tool to monitor drive health going forward.

Frequently asked questions

Does KDiskMark read SMART data?

No, it only measures performance metrics like read/write speeds.

Can I use KDiskMark to monitor drive health?

No, it does not provide health status, temperature, or power‑on hours.

Is there a Linux alternative that matches CrystalDiskInfo’s features?

Yes, smartctl (part of the smartmontools package) can read SMART attributes, show health status, temperature, and power‑on hours, and supports NVMe drives.
